The basic functional unit of human kidney is
(a) nephridia
(b) Henle’s loop
(c) nephron
(d) pyramid.
The basic functional unit of human kidney is nephron. Kidney has four roles that are infiltration, reabsorption , secretion and excretion.
(a) Nephridia is the excretory organ of some lower invertebrates like earthworms.
(b) Henle's loop is a part of nephron. It has the role of absorption of some molecules and ions.
(c) Kidneys are made up of nephrons. Nephrons have same role like kidneys like filtration, reabsorption, secretion and excretion.
(d) Renal pyramids are primely made up of tubules.
